1.0 General
DriveUpgrade-tool helps users to replace old drives with new ABB drives. The
input data is given in white fields. The yellow fields contain data from the
database and/or data entered by the user. The red fields contain important
messages to the user e.g. if the input data is contradictory, the tool gives
"Data conflict" message and informs, which data is in question and what is the
value of the data that has been used for dimensioning.

2.0 Selection methods
Selection can be based on the type code of the existing drive or type code and
additional technical information.

2.1 Selection based on the type code of the
existing drive
User selects the type code of the existing drive from the selection box and
presses "Select replacement drive" pushbutton. Program gets all the necessary
data for the existing drive from the database and uses this data for selecting
the replacements drives.

2.2 Selection based on type code and additional
technical information
If the existing drive is known and it is listed in the selection box, but it is
e.g. not fully loaded, it is possible to optimise the selection of the new drive
by filling in also the "Additional technical information" fields. User selects
the type code of the existing drive and enters also the known technical data (=
load information). Program reads the data of the existing drive from the
database and compares this data to the additional technical data. If there is a
conflict between these sets of data (e.g. the required load current is higher
than allowed for the existing drive), an additional "Data conflict" column will
be shown in the "New drive information" table. This column tells which data is
not valid. If there is no conflict, the "additional technical information" is
used in the dimensioning.

3.0 Load types
The program allows four different load types to be used in dimensioning. Each
type uses different data fields from the database and also the output tables
have different output fields depending on the selected load type.

3.1 Constant, no overloadThis is the default setting in the
program. It is used for constant torque and constant current (load torque stays
constant at different speeds) applications that do not need any momentary
overloadability.

When this load type is selected, the program uses
the highest continuous constant ratings of the drives in dimensioning. The
program checks only the maximum continuous current it must be bigger or equal in
the new drive compared to the existing drive.

3.2 Constant 110% overload 1 minThis is otherwise similar load type as
"Constant, no overload", but it allows 10% overload for 1 minute. I.e. if the
maximum continuous current is 100 A, the drive can give 110 A for 1 min. and
return to 100 A.

When this load type is selected, the program uses
the highest constant rating that allows the momentary 110 % loadability in
dimensioning. The program checks both the maximum continuous current and the
maximum 1 min. overload current. Both currents must be bigger or equal in the
new drive compared to the existing drive.

3.3 Constant 150% overload 1 minThis is otherwise similar load type as
"Constant 110% overload 1 min", but it allows 50% overload for 1 minute instead
of 10%. I.e. if the maximum continuous current is 100 A, the drive can give 150
A for 1 min. and return to 100 A. Examples of applications requiring such high
overloadability are e.g. different cyclical loads such as batch centrifuges,
some extruders and mixers and applications requiring high starting
torque/current.

When this load type is selected, the program uses
the highest constant torque rating that allows the momentary 150 % loadability
in dimensioning. The program checks both the maximum continuous current and the
maximum 1 min. overload current. Both currents must be bigger or equal in the
new drive compared to the existing drive.

3.4 Pump&FanThis load type is used for squared
torque loads (i.e. torque increases proportional to the square of the speed).
Typical applications are centrifugal pumps and fans. When this load type is
selected, the program uses Pump&Fan ratings of the drives in dimensioning. The
program checks both the maximum continuous current and the maximum 1 min.
overload current. Both currents must be bigger or equal in the new drive
compared to the existing drive.

4.0 Select fromIt is possible to refine the search by
giving additional features that are required from the new drive. The existing
drive does not have to fulfil the criteria.

4.1 Stand alone / ModuleThe default settings is stand alone,
but if the drive should e.g. be built into customer specific cabinet, it is
possible to specify that the new drive must be a module. If drive type is
selected to be a module, the program searches only wall mounted drives and
modules. Cabinet built units are excluded. On the other hand, when "stand alone"
is selected, the program excludes the modules.

4.2 6-pulse / 12-pulseThe default setting is 6-pulse, but if
a 12-pulse solution is needed to get lower harmonics, it can be specified here.
If drive type is selected to be a 12-pulse one, the program excludes all 6-pulse
ones. On the other hand, when "6-pulse" is selected, the program excludes the
12-pulse drives.

Please note that 12-pulse drives need a special
12-pulse transformer and 12-pulse option and regeneration cannot be selected at
the same time.

4.3 Non-regenerative / RegenerativeThe default setting is
non-regenerative, but if energy regeneration back to supply network is needed,
it is specified here. If drive type is selected to be a "regenerative", the
program excludes all non-regenerative ones. On the other hand, when
"non-regenerative" is selected, the program excludes the regenerative drives.

Please note that regeneration and 12-pulse option
cannot be selected at the same time.

5.0 Output tablesAfter clicking the "Select replacement"
pushbutton, program creates two tables on the html-page. The first table ("Used
dimensioning data") contains the information of the existing drive that has been
used in the dimensioning. The second table (“New drive information”) contains
multiple rows. The table shows the different suggestions for replacing the
existing drive.

The suggested replacement drives are selected so
that at least two suggestions are given from each product family fulfilling the
selection criteria: next drive that is equal or bigger than the existing drive
and next drive that is smaller. If overloadability is required, the same is done
both for the continuous current and the overload current.

5.1 Dim. criteriaThe "Dim. criteria" field tells, what
have been the selection criteria. E.g. "Next bigger In" means that the drive has
been selected so that its continuous current has been bigger or equal to the
existing drive or to the load current.

5.2 Diff.(%)The "Diff.(%)" shows what is the
margin. E.g. 10% means that the rated value is 10% bigger than required and –
20% that the rated value is 20% smaller than required. If the value is smaller,
the difference value is shown in red.

6.0 Technical data comparisonBy clicking the drive you want to
select, you can see a technical data comparison between the existing and the new
drive. Voltage, selected rated and overload currents and of the other data only
the data with different values is shown.

If the whole technical data including other rated
currents and even the similar and non critical data should be compared, it is
shown, when pushing the "Show all data" pushbutton.
